This is a review.
I suggest you write and put up the next chapter now

Interesting prologue. Funny how in a zombie apocalypse, usually half the group dies, if not all. I did kind of get a little annoyed at the block of text that described every body, so I would suggest that you try doing a separate paragraph for every character. I also saw a couple of periods missing.

This is pretty interesting since I've never read a zombie story like this before.

And as for constructive criticism; I noticed that you had a couple of run-on sentences, especially at the beginning; the big block of words in the middle may discourage some people and is the main character's friend named Ruki or Riku, because you kind of swapped letters a couple times there.

Those are the only things I saw, but I hope you continue this. I'm very interested. :D
